Abstract
In a study of 16 patients with Parkinson's disease, no significant changes were observed in anxiety or fatigue scores after bright light therapy.
- Bright light therapy (BLT) was tested for its effects on depression, anxiety, daytime sleepiness, and fatigue in patients with Parkinson's disease.
- The study was designed as a double-blind, placebo-controlled trial with a crossover approach.
- No significant changes were found in anxiety or fatigue scores after both BLT and placebo treatments.
- Daytime sleepiness scores decreased non-significantly after BLT, but a post hoc analysis indicated a significant decrease in sleepiness for patients with higher baseline scores.
- Future research may explore the impact of BLT specifically in patients experiencing greater daytime sleepiness.
